Scrappy Sea Lord arms cannon again? (7)

I believe the answer is:

reloads

'arms cannon again?' is the definition.

'scrappy sea lord' is the wordplay.
'scrappy' indicates anagramming the letters.
'sea'+'lord'='sealord'
'sealord' is an anagram of 'RELOADS'.

I've seen this clue in The Everyman puzzle in The Observer.
